PURPOSE:To keep inside of the case always and easily humidified by providing, in cooling drafting duct, heat exchanger which can cool and humidify drafting air at the same time. CONSTITUTION:Heat exchanger which is constituted of water pan 4 of which water level L is always maintained constant by automatic water feeding valve 8, evaporator 5 which is submerged under water in the water pan 4, and water absorbing heat exchanging plates 6 of which one ends are submerged in the water in the water pan 4 is provided in cooling drafting duct 1 which leads to the ceiling part from the bottom of the case through back surface part. Being thus constituted, water which is supplied to water pan 4 and cooled by the evaporator 5 is sucked up by water absorbing heat exchanging plates 6 by capillarity, and air flown into drafting duct 1 by the rotation of fan 2 is cooled and humidified at the same time by the heat exchanging plates 6, so that the inside of the case is always kept humdified. |
